Mr. Tom Anderson (whose full name is revealed to be Thomas T. Anderson in Credit Card) is a fictional character from the animated television series Beavis and Butt-Head. His voice is provided by Mike Judge, who says Anderson is based on every middle-aged authority figure he knew growing up in New Mexico. Although he is white on the show, Mike Judge intended for Mr. Anderson to be a black man. The idea was scrapped when a cartoonist didn’t get the memo on making his skin black.
Anderson is an older man, presumably of post-retirement age, who lives with his wife Marcy near Beavis and Butt-Head in Highland. As mentioned in Screamers, Anderson's address is 4120 Woodrow Court. Anderson is very conservative and he frequently makes reference to his days in the military, usually in a futile attempt to teach Beavis and Butt-Head the ethics of hard work and discipline.
Anderson first appeared in Home Improvement. He instructed Beavis and Butt-Head to paint only the trim on his house. After sniffing paint thinner, they paint the outer walls, windows and roof of his house with heavy metal-related graffiti, and they paint his cat’s bottom. They also set fire to one of his shrubs. The episode ends with Beavis and Butt-Head driving Anderson’s lawn mower down the street.
He is primarily the target of pranks, although occasionally Beavis and Butt-Head attempt to do Anderson a favor. In Washing the Dog they develop a get-rich-quick scheme that involves being nice to an old person in order to get into his will. After concluding that Anderson might die soon - by the rather direct method of asking him - Beavis and Butt-Head offer to wash Anderson’s dog. They take his poodle to the laundromat and stuff it into a washing machine. This scene caused many complaints from parents, especially when at least one child put a dog into a washing machine after apparently being influenced by the show. Ultimately, the episode was banned from TV.
Beavis and Butt-Head’s antics detrimental to Mr. Anderson also include:
Anderson is also very near-sighted. When he meets Beavis and Butt-Head, he nearly always asks if they were responsible for some sort of ludicrous prank or general vandalizing of his property (e.g. “Are you the boys who painted my cat’s butt?”, "Say, ain't you the kids that have been whacking off in my tool shed?", etc.), to which they reply with a firm “No,” whilst snickering, making it obvious they are indeed the guilty parties. Anderson’s poor vision and memory problems allow them to continually get away with anything they do to him, as he never recognizes them. In one memorable episode, the two disguise themselves by wearing horn rimmed glasses, which fool Anderson so completely that he doesn’t even ask if they are responsible for some misdeed. In Home Improvement Anderson gives a completely inaccurate description of the two to the police: “One of them calls himself Butt-Hole. And the other one’s name is Joe, I think...I believe they were Oriental.”
In the movie Beavis and Butt-Head Do America, the dimwitted duo cause mayhem and chaos involving Anderson right from the start. He mentions that kids have been “whackin’ off in my toolshed”, which the pair giggle at, implying they have been doing it. Other antics by Beavis and Butt-Head during the movie include:
Later in the movie he returns to Highland, having been proven innocent. Hank Hill from King of the Hill may be based off of Anderson.
